3.0 INSTALLATION
CAUTION: Local plumbing and electrical codes must be observed .
The following guidelines should be met at installation.
1. Customer is to provide properly sized wiring to the distribution pump control enclosure.
2. Place the pump system on firm, level floor and anchor to the floor to prevent movement
from vibration or bumping.
3. Inlet piping and / or hoses from the storage tank to the pump system should be equal to
or greater in diameter than the inlet piping on the pump system.
4. Outlet piping and / or hoses of the pump system should be equal to or greater in
diameter than the outlet piping on the pump system.
5. Locate the pump control on a wall as close to the pump system as possible. When
installing a distribution pump along with an AmeriWater Central Water System, refer to
the Plumbing and Instrumentation Diagram (P&ID) for the best location and where
connections are made.
6. Follow all local plumbing and electrical codes.
7. After guidelines have been met, connect the distribution pump wiring to the motor
contactor located in the control panel (refer to the control wiring diagram provided in
this manual and with the distribution pump control). Connect the three phase or single
phase power source to the Main ON/OFF disconnect switch located inside the control
panel.
CAUTION: For three phase systems, check the rotation of the pump. Turn the main
power disconnect to the on position and observe the rotation of the pump.
When facing the motor end, correct rotation is in the clockwise rotation. If
the rotation is backwards, switch two pump wires on the motor contactor
inside the panel.
4.0 START-UP
1. Open the inlet and outlet valves to the pump and allow the water in the storage tank to
“flood” the inlet of the distribution pump. If the storage tank does not have water in it,
fill it to above the lowest float switch before attempting to use the pump.
2. To prime the pump, close the discharge valve. Remove the vent plug. For 2SV only,
fully unscrew the pin located in the drain plug. Open the suction valve until liquid flows
out of the vent plug opening.
NOTE: Place a loose rag over the open vent port to prevent large amounts of liquid from
being sprayed on the pump and adjacent equipment.
